Application fi1ed December 15, 1911. Serial No. 666,014.

To all whom it may concern Be it known that 1, JOHN M. STUBBLE- FIELD, a citizen of the United States, residing at Pawhuska, in the county of Osage and State of Oklahoma, have invented a new and useful School Seat and Desk, of which the following is a specification.

This invention relates .to'combined school seats and desks and has for its object to provide a device of this class which is practically indestructible and which is so arconstructed as to present ready adjustability of the height of the seat from the floor in order to adapt the seat to pupils of varyin ages.

A further object of the invention is to provide a novel arrangement for limiting and varying the amount of swing of the desk and seat in the stationary base.

A further object of the invention is to provide a simple arrangement for adjusting the angularity of the seat.

A further object of the invention is to provide a simple and effective construction for adjustin the height of the desk and the angularity thereof irrespective of the height of the seat so as to adapt the deskto pupils of varying agesirrespective of the height of the seat.

With all these objects in view the invention consists in the novel construction of a combined school seat and desk, which is of a material preferably metal, in such manner as to produce a strong, rigid, durable and eflicient construction and which is adjustable so that the height of the seat can be adjusted in relation to the floor, the angularity of the seat can be adjusted, while the heightand angularity of the desk can be adjusted independently of the other adjustments; and the invention further consists in the novel and simple construction which provides for a compact folding of the seat and the desk.

The invention also consists in certain other novel details of construction and in combinations of parts, all of which will be first fully described and afterward specifically pointed out in theappended claims.

Referring to the accompanying drawings: Figure 1 is a perspective view of a combined school seatand desk constructed in accordance with this invention. Fig. 2 is an elevation partly in section illustrating the seat and desk in a folded position. Fig. 3 is an enlarged fragmentary vertical sectional view taken through the upper portion of of the slidable base. Fig. at isa transverse sectional view taken on line lt of Fig. 3. Fig. 5 is a transverse sectional view through the seat back taken on' line 5-5 of Fig. 1.

- Fig. 6 is an enlarged transverse sectional view taken on line (3-6 of Fig. 2. Fig. 7 is a rear elevation of the T portion of the supporting base,and Fig.8 is a fragmentary elevation of the upper portion of the supporting base.

Like numerals of referenceindicate the same parts throughout the several figures in which;

1 indicates the combined seat and desk which comprises the seat 2, back 3, desk l, book shelf 5, base 6 and vertically adjustable supporting post7. The base 6 is flanged at 8 to provide a large base or support and said flange 8 is preferably secured in position by screws 9. Extending upwardly and cen trall of the flange 8 is the tubular portion 10 o the base, said tubular portion 10 being provided near its lower end with a pair of oppositely disposed vertical slots 11 designed to accommodate a transverse bolt-10' which transverse bolt 10 secures within the tubular portion 10 a stop 12 as shown in Fig. 3. Entering the tubular portion 10 is the ad justable post 7 which, as will appear from Fig. 3, engages the stop 12, the vertical adjustment of the said post 7 being effected by means of the transverse bolt 10' within the slots 11 as will be apparent from an inspec= tion of Fig. 3. In order to secure the post 7 within the tubular portion 10 of the base a set screw 13 is provided, while there is also provided on the said post 7 a sleeve 14: which carries a set screw 15 for securing the said sleeve 14 against movement on the post 7, the lower portion 16 of said sleeve being enlarged as shown in Fig. 3 to encompass the Epper end of the tubular portion 10 of the ase.

Referring particularly to the upper end of the tubular portion 10 of the base and in this connection to Figs. 4 and 8 it will be seen that the upperend of the tubular portion 10 of the base is provided with three vertical extensions 17 18 and 19, while it will be seen that a set screw 20 is carried in the enlarged portion 16 of the sleeve 14, the said set screw 20 entering the said vertical extensions on the upper end of the tubularportion 10 of the base as shown in Fig. 4. and for a purthe permanent base and the lower portion pose which will be presently described. At that an offset or staple-like metal strap 49 the upper end of the supporting base 7 'is securely fastened at 50 to the back 3 at the provided a cross piece 21 as shown in Fig. 7, lower edge thereof 18 provided to carry a while a flange 22 is provided at each end of clip 51, which clip surroundsand embraces the said cross piece2l, saidflanges being the supporting post 7 1n the manner as provided with a plurality of elongated slots shown in Figs. 2 and 6. 23 as shown in Fig.2. Having thus'fully" described the invention Referring now, to the back 3 it will be seen its operation is asfollows: As will be apparthat the same is bordered with an angle-iron ent fronr an inspection "of Figs. 1 and 3 the border 24, and referring to Fig. 2 it will be post 7 is'adjustable'in relation to the permaseen that the said angle-iron border of the nent base 6'in such manner that the height back 3 is boltedto the flanges 22 on the ends I of the seat 2 can be adjustedvertically in of the cross piece 21 by bolts 25. It will be relation to the floor. It will-also be seen also seen by reference to Figs. 1 and 2 that j that when it is desired to maintain the post a piece of strap metal 26 is securely bolted 7 against rotation in the tubularportion'l0' or riveted at 27 to the lower portion of the of the base the set screw 13 is caused to enangle-iron border 24 of the back 3 which is gage the said post 7 to lock the post 7 and formed into a loop 28 to which loop the seat tubular portion lO flrmly together. When, 2 is pivoted at 29, while a cross rod however, it is desired to permit rotation of 20 connectsthe two loops 28 in such manner as the post 7 in relation to the tubular portion -5 to engage the'inner end of the seat 2 when 10 of the base the same can be accomplished the said seat is in an open position as shown by loosening the set screw 13 and tightening 'in Fig. 1. The said strap metal 26 extends the set screw 15 in the sleeve '14, thus locking rearwar'dly and upwardly from the bottom thesleeve 14 to the post 7. The set's'crew 5 edge of the back 3-and is bolted at 31 to the 20 in the enlarged portionof the sleeve 14 90 flanges 22 on the cross piece 21 of the suppasses inwardly in' the manner as. shown in porting base 7, while the book shelf 5 is Fig. 3 and lies between two of the upwardly rigidly fastened-to the said str metal 26 at the point 32 and to the angle-iron border 5 of the back 3 at'the point33. Above the book shelf 5' the strap metal 26 is turned toward the seat 3 to provide an inclined piece 34 which is provided withinwardly extending pins 35. The extremeupperend 35 of the strap metal piece 26 is bent into engagement with the angle-iron border of the back 3 to which itis secured at 36 in the rmannerias shown in Figs. 1 and 2. Secured nearthe upper edge (if the back 3 at both sides thereof is a piece 37' which extends downwardly and which is secured at38 tothe strap iron piece26, a-sl'ot 39 being provided between said piece 37 and the angle ironborder 24 of the back 3. v Referring now to the desk 4 and: particularly to Fig. 5, it will be seen that the same comprises an angle-iron border 40 carrying a transverse rod 4lwhich transverse rod 41 passes through the slot 39 inlthe back 3, while flanges 42 are provided on said rod 41, said flanges 42 being provided with inwardly extending pins 43 which enter perforations are in this position the post 7 and its sleeve 5 I tubular portion 10 of the base or until the set screw 20 engages the upwardly extending extensions Y17 and 19 which extensions act as stops to limit the extent of rotation as 00 will be apparent from an inspection of Fig. 4. tVhen, however, the sleeve 14 is reversed in such manner that the said screw 20 enters. between the upward extensions 17 and 18 the extent ofrotation is'rest 'ricted as the 5 said extensions 17 and 18 are arranged closer together than the extensions 17 and 19. When; however, the set screw 20 enters between the extensions 18 and 19 all rotation of the post 7 in the tubular portion 10 0 is prevented as will be clearly apparent from an inspection of Fig. 4. -The vertical ad ustment of the post 7 being effected in the manner as just described the 'angularity of" 25 and 31 in the flanges 22 on the cross piece 21 of the post'7, said bolts 25 and 31 passing 44 in the parts 24 and 37 adjacent the said through the elongated slots 23 in said flanges slots 39, a nut 45 on the rod 41 securing the allow a suflicient angular adjustment of the j I parts together in the manner as shown in back 3 to meet all ordinary requirements. 20 Fig. 5. A pair of braces 46 pivoted at 47 The angle of the seat 2' however is adjustto the border 40 of the desk 4 and, of course, able independently .of the back 3 by means thereunder, support the'same in the manner of an alteration of the pivotal point .29 in the as shown in Fig. 1, the said braces 46 being 'loop 28 in the manner as is apparent from provided at their lower ends with a plu ,p 1 a.

In order to adjust the height and angurality of notches 48 which engage the pins 35. on the portion 34 in order to adjustably. larity of the desk 4 irrespective of the height hold the desk 4 in the desired adjusted posiand angularity of the back 3 the nut 45 onthe cross bar 41 (Fig. 5') is slacked away tion. v @5 Referring now to Fig. 6 it will be. seen until the pins 43 on the flanges 42 are out of 130 the back 3 is adjusted by means of the bOltS engagement with the perforations 44 adjacent the elongated slot 39. Said transverse rod'41 and its flanges 42 are then capable of vertical adjustment in the slot 39 and can be locked in any desired position upon the entrance of the pins 43 on the flanges 42 in any desired perforations 44 adjacent the slots 39. By means of this construction the desk 4 can be raised or lowered as desired irrespective of the height or adjustment of the seat and back, While the angularity of the desk 4 is controlled by the notched sup ports 46 in engagement with the pins 35 on the piece 34.

Having thus fully described the invention itis apparent that the same is capable of changes and alterations which would come within the limit and scope of this invention and I consider myself clearly entitled to all such changes and modifications as fall within the terms of the following claims.

What I claim as new and desire to secure by Letters Patent of the United States is 1. In a device of the type described, the combination with a seatand its supporting means therefor including an up- Gopies olthis patent may be obtained for five cents each, by addressing the back, of I right having at its upper end a transverse member provided at its ends with flanges, a member having pivotal supporting connection with said seat and fixed connection with said back, means eil'ecting adjustable connection between said flanges and said scatpivotal-supporting member, and means efi'ecting adjustable connection between said flanges and said back.

2. In a device of the type described, the combination with a seat and its back, of supporting means therefor including an upright having at its upper end a transverse member provided at its ends with flanges having slots therein, a member having pivotal supporting connection with said seat and fixed connection with said back, and ad usting screws engaging, said slots of the flanges,

eifecting adjustable connection between said pivotal supporting members and said flanges, and adjustable connection between said back and said flanges, respectively.
